I'm not defending Wasabi. Wasabi has flaws in the way it builds Tor circuits, but the fact is that Samourai used the same Tor circuit for everything—I pointed out the bug here myself. And this is also acknowledged by the developer you mention—who, by the way, isn't actually named that. Wasabi's handling of Tor circuits is light-years ahead of what Samourai did. Don’t fool yourself—I audited Samourai’s code myself.
